Gamba stores user data, including username, passwords, money, and assets using SQLAlchemy. Authentication and signup is handled in account.py. Gamba uses JWT's to manage user sessions. A token must be passed in most games to play. Gambling games endpoints are stored in games.py.

The Stock features use real time data using the Finnhub API. Live quotes are streamed using Websockets. Purchases are delayed and are batched, which seems reasonable as there is no actual supply / demand.

Since Finnhub does not have streaming for option chain data, this will be polled and cached using Redis. Option chain data will also be delayed. I will probably only support option chain for SPY, which is around 8 megabytes per poll.
